The winter-like air pressure distribution will gradually loosen, and tomorrow and the day after tomorrow will be full of spring-like warmth.

2026/02/19 09:09

There is a low pressure system with a front over the sea east of Japan, and it is moving north-northeast.
On the other hand, there is a high pressure system on the continent that spreads toward western Japan, and the area around Japan has a winter-like atmospheric pressure distribution centered on northern Japan.




Currently, snow is falling in northern Japan and Hokuriku, mainly on the Sea of Japan side, but it is sunny in many places from the Pacific side of eastern Japan to the Kyushu and Okinawa regions.



Today, high pressure will gradually spread from the west, and the winter-like pressure distribution will loosen.



Western and eastern Japan is expected to have many sunny days.
Although the number of places where it will snow in northern Japan and Hokuriku will gradually decrease, please be aware that it is expected to snow in the morning and there will be some places where it will snow.
The daytime temperature is lower than yesterday, and in some places in Kyushu it is higher than normal, but in many places nationwide it will be at or below normal.



Tomorrow, the winter-like pressure system will loosen and high pressure will gradually spread, but a weak low pressure will advance near the southern coast of Honshu.



Moist air will enter western and eastern Japan, making clouds more likely to spread, but no major collapse is expected.

Even in northern Japan, the snow will stop, and it will be sunny in many places. After that, the high pressure will gradually expand into the day after tomorrow, and it will be sunny in many places.
Also, as warm air enters from the south, the temperature will rise tomorrow and the day after tomorrow. Tomorrow, the weather will be normal to late March, and the day after tomorrow it will be even warmer, with the weather expected to be from March to April.

"Haruichiban" in the Hokuriku region, first announcement of the season

2026/02/18 17:04

Today, February 18th (Wednesday), ``Spring Ichiban'' blew in the Hokuriku region. This season will be the first spring announcement in the country.
This year's first observation of spring in the Hokuriku region was 15 days later than last year's February 3rd.

Currently, a low pressure system is located in the northern part of the Sea of Japan, and is developing and moving east-northeast. As a result, rather strong southerly winds were blowing towards the low pressure system in the Hokuriku region. The temperature is also about 3 to 4 degrees higher than the previous day, the 17th.
Today, in Kanazawa, a maximum wind speed of 10.1 m/s was observed at 11:00.



"Haru Ichiban" refers to the warm, strong wind from the south that blows for the first time during the transition period from winter to spring. The Japan Meteorological Agency describes it as a warm (slightly) strong wind from the south that blows for the first time over a wide area (about the size of a local forecast area) between the first day of spring and the vernal equinox.



The developing low pressure system is expected to move towards Hokkaido into the evening, and the Hokuriku region will then see winds shift to the northwest and temperatures will drop.
The snow is expected to gradually increase into the evening.
Also, strong cold air flows into the sky, making the atmosphere extremely unstable. Cumulonimbus clouds will develop locally. In the Hokuriku region, watch out for thunderstorms, tornadoes, severe gusts, and hail from late tonight.

Weekly weather: Spring warmth throughout the country during the three-day weekend; weather goes downhill during the second half of the holiday

2026/02/18 07:32

From now on, around the 21st to 23rd, which will be a three-day holiday, the area around Honshu will experience spring warmth.



Tomorrow, the 19th (Thursday), there will be a temporary winter-like atmospheric pressure pattern around Honshu. Snow will fall in the morning on the Sea of Japan side of northern Japan and Hokuriku, and there will be strong winds and snow in some places. However, the area of snow will become narrower around noon, and the weather will start to improve.

From the 20th onward, warm air will enter the Honshu region from the south, and by the time the 21st (Saturday) marks the start of the three-day holiday, some places will experience spring warmth. Temperatures in northern and eastern Japan are expected to be well above normal, and even in western Japan, there are some places like Fukuoka and Kagoshima where temperatures are expected to approach 20 C.
In areas with heavy snowfall, rising temperatures can cause snow to melt more rapidly. Please be careful of avalanches and deterioration of road conditions due to melting snow.

In the latter half of the three-day weekend, the area around Honshu is expected to be affected by fronts and low pressure. The weather will turn downward from the west, and there is a chance of rain around the 23rd (Monday), which is a public holiday, mainly on the Sea of Japan side. Due to the effects of the low pressure, the spacing between the isobar lines is narrow, and the wind is likely to be strong, resulting in torrential rain in some places. During the second half of the three-day weekend, it is necessary to pay attention to the trends of low pressure systems and fronts.

Western Japan and the Pacific side of eastern Japan will continue to have many sunny days, and the drought trend will continue. Please try to conserve water as much as possible. Additionally, the dry air will continue to make fires more likely, so please be careful when handling fire.
It is expected that the amount of cedar pollen scattered will increase as the temperature rises. When going out during the three-day holiday, it is better to take precautions such as wearing a mask wherever you go.

Tomorrow, the 18th (Wednesday), a low pressure system will pass through northern Japan. Wind and snow will become stronger from the Sea of Japan side of northern Japan to Hokuriku.

2026/02/17 21:05

Tomorrow, the 18th (Wednesday), a low pressure system accompanied by a front will pass through the Sea of Japan. As a result, there is a risk of rough weather from the Sea of Japan side of northern Japan to the Hokuriku region.



Tomorrow, a low pressure system accompanied by a front will move near Hokkaido, and the weather from northern Japan to Hokuriku will change to snow and rain in the afternoon. Warm, humid air will flow towards the front, causing rain and snow clouds to develop, and there will likely be some localized thunderstorms. Please be aware of changes in the sky as strong wind gusts such as tornadoes may occur.



As the front moves southward, strong cold air is expected to temporarily flow into the Honshu region. As a result, there is a risk that the snow will become heavier and snowfall will increase rapidly, mainly along the mountains from northern Japan to Hokuriku, into the night of tomorrow, the 18th. The area of snow will also spread to the northern Kinki region and along the mountains in the San'in region.
In addition, there is a risk of strong winds and blizzards, especially in coastal areas. Please be aware of worsening visibility due to snowstorms and rapid accumulation of snow, and be careful of high waves in coastal areas.



By the morning of the 19th (Thursday), the day after the date changes, the snow is expected to gradually narrow down and stop in many places. However, after the low pressure system passes, the winter cold will return temporarily. The temperature tends to fluctuate significantly, so please try not to get sick.

Western Japan has the lowest rainfall ever recorded as widespread areas continue to be dry; watch out for large-scale forest fires

2026/02/17 16:39

The Pacific side of northern and eastern Japan and western Japan are experiencing record low rainfall.
Since mid-November last year on the Pacific side of eastern Japan and western Japan, and since early January this year on the Pacific side of northern Japan, conditions have remained low, making it less susceptible to the effects of low-pressure systems.

On the Sea of Japan side of western Japan and the Pacific side of western Japan, the average precipitation in January of this year was 41% and 9%, respectively, the lowest rainfall for January since statistics began in 1946.

The Pacific side of eastern Japan and western Japan are expected to continue experiencing low precipitation for about a month. In addition, although rainfall on the Pacific side of northern Japan is expected to be near normal for the next month or so, it is unlikely that the current low rainfall will be resolved.

Please be careful about managing crops and water.
In 2020, with record low rainfall, many large-scale forest fires occurred nationwide from winter to spring. From January to May, the weather is particularly dry and windy, making forest fires more likely. Please be careful when handling fire.
Also, the water storage rate of dams is decreasing in various places, leading to water shortages, so be sure to conserve water.



Precipitation amount for the past 90 days (November 19, 2025 to February 16, 2026).
Many locations in the Kanto, Chugoku, Shikoku, and Kyushu regions are below 30% of normal levels. In particular, rainfall is extremely low at 11% in Maebashi and 12% in Kochi.



Precipitation amount for the past 45 days (January 3 to February 16, 2026).
In many places on the Pacific side of northern and western Japan, the average level is below 30%. Especially in Sendai, the rainfall is 8%, which is extremely low compared to the average year.

Weather today, the 17th (Tuesday): Although the sun is shining widely, the temperature has not risen compared to the previous day.

2026/02/17 06:29

Today, the 17th (Tuesday), the area around Japan will be covered by a mobile high pressure system, so many places will be exposed to sunlight.



Sunlight reaches a wide area from northern Japan to western Japan, including the Sea of Japan side. The sky will be dominated by clouds in the southern Kanto region until the morning, but the weather will start to improve in the afternoon.

In Hokkaido, snow begins to fall late at night, and there are places where snowstorms can occur, so be careful.

Okinawa will experience rainy weather until the morning due to the influence of a low pressure system. The weather will improve in the afternoon, so please be careful not to leave your rain gear behind when you return.

Even when the sun shines during the day, the temperature rises modestly. In many places, the temperature will be lower than the previous day, and from eastern Japan to Chugoku and Shikoku, the maximum temperature will be around 10c, which is expected to be cold for this time of year. Please keep warm when going out.

1st Cherry Blossom Bloom Forecast: Will this year be normal or early blooming Forecast for Tokyo on March 21st

2026/02/16 21:56

Our company Sunny Spot will announce the first cherry blossom bloom forecast.

From now on, temperatures will rise over the three-day weekend this weekend, making it warmer than normal in spring.
Then, as warm air tends to flow into Japan until March 2nd (Monday), the Japan Meteorological Agency has issued an "early weather advisory regarding high temperatures," and temperatures are expected to be significantly higher than normal in northern Japan and the Kanto region.
As a result, the flowering date is expected to be around normal or earlier than normal across the country, and in northern Japan, the flowering date is expected to be approximately one week earlier than normal.



The top blooming area in 2026 is expected to be around March 21st in Kochi in western Japan and Tokyo in eastern Japan. By the end of March, cherry blossoms will be blooming widely from Kyushu to Kanto, and there will be some places where the cherry blossoms will be in full bloom.
In some places in the Hokuriku and Koshin regions, the flowering date may be delayed to early April.

In April, the cherry blossom front will move towards Tohoku, and the cherry blossoms are expected to start blooming in Sendai in early April and in Aomori in mid-April. The cherry blossom front is expected to reach Hokkaido in late April, and cherry blossoms are expected to bloom in Wakkanai and Abashiri in early May.

In the Kanto region, snow will fall mainly along the mountains from tonight until dawn tomorrow.

2026/02/16 19:30

In the vicinity of Japan, the atmospheric pressure is high in the west and low in the east, between a low pressure system moving east-northeast around the Kuril Islands and a high pressure system overhanging the continent.
Also, in the sea near the Izu Islands, a shear line is formed, where the northeast wind that wraps around the Chubu Mountains collides with the northwest wind. Due to this shear line and the cold air in the sky, clouds are likely to develop in the Kanto region starting tonight, and snow and rain are expected.

Currently, it is raining in some places in the northern Kanto region and Chiba Prefecture. After this, the temperature will drop late at night, so rain and snow will gradually spread from early evening today, the 16th (Monday) to early morning on the 17th (Tuesday).




There will be snowfall in some places, especially along the mountains and in the mountains of the Tama region of Tokyo and western Kanagawa Prefecture.
There is a possibility that there will be snow in the 23 wards of Tokyo, and it is not expected that it will snow, but if the ground temperature is lower than expected or if there is more precipitation, there is a possibility that there will be snow in the 23 wards.

Although it is expected to stop during the commuter hours on the morning of tomorrow, the 17th (Tuesday), there are some places in the mountains and inland where it will get colder in the morning, so please be careful of icy roads.


[Snow Forecast]
The 24-hour snowfall expected from 18:00 on the 16th to 18:00 on the 17th is high in some places.

[Weather from the beginning of the week] The cold will return in the first half of the week, but the next weekend will also be full of spring warmth

2026/02/16 11:30

To the north of Hokkaido and south of Shikoku, there is a low pressure front accompanied by a front that is moving northeast and east.
On the other hand, there is an anticyclone on the continent that is spreading toward the East China Sea.

Today, warm air entered the area around Japan, and during the day it was as warm as late March to late April, with temperatures nationwide being more than 6 degrees Celsius higher than normal.





Tomorrow, the 16th (Monday), a developed low pressure system will move toward the Sea of Okhotsk.
Also, a low pressure system moving eastward south of Japan will move over the southeast coast of Kanto.
A dominant high pressure system will extend eastward from the continent, so a winter-like pressure distribution is expected.
The daytime temperature will drop into the day after tomorrow as cold air replaces it from the north.
Tomorrow, there will be snow and rain in many places along the Sea of Japan coast from Hokkaido to the San'in region.
Although it is sunny in many places on the Pacific side, it tends to rain in the Kanto region from the evening onwards due to the influence of a weak atmospheric pressure trough.
There may be some snow mixed in for a while.
Please be aware that it will snow at night along the mountain, and there is a possibility of snow accumulation.


Then, the weather over the weekend is




On the Pacific side, there are many sunny days towards the middle of the week, and the temperature will drop around the 17th (Tuesday), and the cold will return.
There will be more cloudy days in the second half of the week, but temperatures will rise and many places will experience spring-like warmth again over the weekend.
Please take care of your health as there are large differences in temperature from day to day and between morning and evening.
Also, please be careful when handling fire as there are many places where the air is dry.

On the Japan Sea side, there are many days when it snows and rains, mainly from Hokkaido to Hokuriku.
A low pressure system and front are expected to pass through northern Japan on the 18th (Wednesday) in the middle of the week.
Please be aware that there is a risk of stormy weather with increasing snow and wind, especially on the Sea of Japan side of northern Japan.
Temperatures will rise over the weekend, bringing the warmth of spring.

Temperatures are rising in various parts of the country and spring is in full swing. In areas with heavy snowfall, be careful of melting snow.

2026/02/15 07:08

Today, the 15th (Sunday), a low pressure system and front are expected to move north of Hokkaido. As warm air flows towards this low-pressure system, temperatures are expected to rise across the region, bringing the weather into the early spring weather.



During the day, it will be as sunny as late March to early April in many places, and you won't need a jacket. There are many places where it will be a good day to go out. It's going to be a day with a big difference in temperature between morning and evening and during the day, so please be careful of the temperature difference.
Also, snow melting is expected to progress in snowy areas. Be careful of snow melting disasters such as falling snow from roofs, deteriorating road conditions, and avalanches.

From night onwards, it gets colder as cold air flows into northern Japan. If you are returning home late, please don't forget to take measures to protect yourself from the cold.
